I have a question to see if im doing this correctly with regards to using Scathing Tirade against minions, and apologies if this has been answered. If my understanding of the rules are correct if you use scathing tirade against a group of minions they are effectively one target.

Example you make a roll for tirade and generate 2 success , and 3 advantage against a group of 4 minions. If I am correct then you can cause 1 strain damage to the group as a whole with the success, since the rules treat the group as a single target, the other success cannot be used to select another minion in that group as it is the same target, the advantages can then be used to cause additional strain damage as normal, so a total of 4 strain damage is caused, and the other success could only be used if another enemy is around.

Alternatively does Scathing Tirade allow you to select another "Enemy"

Ive always favored the first option here but the wording of tirade only specifies another enemy, and since Scathing Tirade isnt an attack I may be incorrect here in which case multiple succeses coukd be applied to multiple minion grouo members. If so Ive been wrong in making my players use the success on another miniion group/rival or nemeisis, its not come up often.

Has anyone seen a ruling on it or what do you guys think

Scathing Tirade them is just like shooting them - a group of 4 minions is treated as one target. If you have multiple valid targets in range, Minion Group A, Minion Group B and Minion Group C, (or single targets like rivals or Nemesis) you can target them too with your extra. But targeting Moe in Minion Group A, then Larry in Minion Group A and then Curly in Minion Group A doesn't work.
